Alien Jellyfish Bodycam Attack

Single continuous 15-second shaky handheld bodycam POV from an armed guard on the deck of a small ship, looking over the dark metal railing at choppy gray ocean under heavy overcast skies, flat cold daylight, misty B-movie horror atmosphere. A large translucent tentacled alien creature (half-jellyfish, half-squid) with pale rubbery skin, thick dangling tentacles and a bulbous mantle bounces erratically across the water surface like a living target 12-18 meters away. The guard fires his rifle multiple times at the moving creature while yelling panicked into his radio: “It’s bouncing on the water! I’m engaging! What the hell is that thing?!” Each shot makes the creature splash and disappear underwater. The guard rushes forward to the edge of the railing, breathing hard, sweeping the camera left and right frantically searching the dark water, still talking on radio “It went under! I can’t see it anymore… where the hell did it go?!” Suddenly the creature erupts violently from the water in a massive splash right in front of him — extreme jump scare — multiple thick tentacles shoot up, wrap around his body and rifle, lifting him off the deck as he screams in terror. The creature drags him struggling and kicking over the railing and pulls him down into the dark ocean. Photorealistic, high detail, intense cinematic tension, subtle film grain, realistic water physics.
